This PR fixes the links in the concepts section. Most of the links are
not dead links in English version because there are redirects for them.
However, these links will be broken when localized to any languages
other English.
Where appropriate. this PR also wraps some long lines which are
unfriendly to any localization team that try to catch the differences
between revisions.
Delete a reference to the "node.kubernetes.io/out-of-disk" taint, which
Kubernetes 1.14 deleted (commit 8f87e71e0cc3a2b714291ecd7210dfd8f4de33d6).
Document that the DaemonSet controller adds a toleration for the
"node.kubernetes.io/pid-pressure" taint since Kubernetes 1.14 (commit
ad6e3617d3e92f47fa0874ca258ffe31d1d2ff4c).
